Hi all, i m not good with english, i made a video to show this.

why apps made in b4i show a black screen when you touch on the icon?
here is a video, its my phone (iphone 4s)

i see that only on b4i apps, all anothers are normal, on video i open 5+ apps to show.
i m tryed this tutorial
https://www.b4x.com/android/forum/threads/how-to-add-launch-images-in-b4i.55597/#content
but no success, i edit B4iProject-Info.plist file, when i compile my app the code of iphone 4s is removed, and if i put read only the app dont compile.
code iPhone 4s
B4X:
<dict>
    <key>UILaunchImageMinimumOSVersion</key>
    <string>7.0</string>
    <key>UILaunchImageName</key>
    <string>Default</string>
    <key>UILaunchImageOrientation</key>
    <string>Portrait</string>
    <key>UILaunchImageSize</key>
    <string>{320, 480}</string>
  </dict>

Step #1: Close the IDE.
Step #2:
Edit B4iProject-Info.plist file. It is located in the installation folder under Project subfolder.
You need to update the file in the installation folder (under Program Files).
Hmm thx this works now.
now i see a red image very fast(it close fast), later i see the black for 4/5s and later 4/5s i see my layout/page
i will try find a way to clear my Application_Start
